I have a Google #.
I always give it to those whom I dont want to give my ‘main’ number. Businesses that I suspect will sell my number.
When a call comes in, it gets forwarded to whatever number I want it forwarded to. If I dont answer, it goes to voicemail and then I get a text (voice recognition) with the message.
It is a great screening tool.
So if I get repeated calls from a certain number, I can block it.
